Input: stmfts - fix reference leak in stmfts_input_open
[ Upstream commit 26623eea0da3476446909af96c980768df07bbd9 ]
pm_runtime_get_sync() will increment pm usage counter even it
failed. Forgetting to call pm_runtime_put_noidle will result
in reference leak in stmfts_input_open, so we should fix it.
